Good but had several large clumps of a mud-like substance mixed in.

Description says "looks like small/medium perlite" but there are some pieces as big as 3/4 "
Other than that its a pretty good deal.

Some of the large pieces I don't care for but everything else is fine.

I don’t think this will help much for the intended use of adding aeration to a mix. The particles are way too small and fine, I have a feeling they just made my soil even more dense. I’m sure they add some valuable trace minerals and silica, though.
